PIG-TROUGH.

i SPECIFICATION forming part of Letters Patent No. 436,956, dated September 23, 1890.

Application filed November l0, 1837.

To all whom it may concern.-

Be it known that l, SUSAN EMMA SMiTrLa citizen of the United States of America, re siding at Minneapolis, in the county of Ottawa and State of Kansas, have invented a new and useful Improvement in Pig-Troughs, of which the following is a specification.

My invention has relation to improvements in pigtroughs, and the object is to improve existing articles of the kind; and with this in view my invention consists in the novel construction of parts and their combination, as will be hereinafter more fully specied, and specially as I have particularly pointed out the same in the claims.

I have fully and clearly illustrated my invention in the accompanying drawings, wherein- Figure l is a perspective of the trough,one end piece, one of the platform-boards, and the top frame being removed to better show the construction. Fig. 2 is a perspective of the top frame and cover of the valve-chamber of the trough. Fig. 3 is a view of one of the platforms. Fig. 4 is a view of one of the end gates or boards. Fig. 5 is a view of the valve mechanism.

Reference being had to the drawings, L des ignates substantial base-pieces, made long enough to receive and sustain the platforms which are secured to their projecting ends. These base-pieces may be supported on longitudinallyarranged sills Z and the parts securely fixed together. In the basempieces are formed mortises, in which the tenoned ends of standards A are set and secured. These standards Aconstitute the means for holding the sides of the trough in Vertical fixed position, as seen in Fig. l of the drawings.

On the extended parts of the basepieces are laid and secured platformpieces K, which may be cut away, as at 2, to set about the standards and so that the inner edge of the board shall set snug against the edge of the trough.

J designates the sides of the trough, and I the bottom, which are tongued and grooved together, as at 3, in order that they may be held water-tight.

The inner faces of the side pieces and bottom are provided with grooves 4, in which the tongues 5 of the end pieces G and the inter Serial No. 254,333. (No model.)

mediate partition Il are arranged, as seen in Fig. l of the drawings.

In the partition H are formed apertures 6, which constitute the water ports or ways, through which the water nds its way from the valve-chamber.

On the tenonedends 7 of the standards A are mortised and secured cross -pieces B, which constitute the means for holding the standards A iirm in position and the trough from spreading, and also, in conjunction with the shorter cross-piece C, serve to prevent the animals from getting` bodily into the trough.

Arranged longitudinally over the middle of the trough and secured to the several crosspieces is a top rail D, which is let into the crosspieces, as at 8, and has its ends fastened by bolts to the two end cross-pieces, substantially as shown in the drawings.

The short cross-piece O is secured to the trough by bolts- 9 let into the side piece of the trough, and the top rail D is out away on its under side, as at 10, to give plenty of room for the head of the animal when drinking.

To keep dirt and other outside objects from getting into the valve-chamber, I put a stationary cover E on one side and secure it there by any suitable means, and on the other side I arrange a detachable piece E. This latter E is held in place by two blocks F, fixed at an angle in the faces of the crosspieces B, to take the lower edge corners of the cover, and then secured by hooks Il, engaging staples I2 in the top rail. By simply unlocking the hooks the lid may be removed, and it can be replaced by setting the lower edge in the angle of the blocks and fastening the hooks in the staples, as seen in Fig. 2 of the drawings.

The end partitiompieces are held firm and securely in theirv seats by bolts 13 let up through the bottom into the respective pieces,

IOO

an eccentrically-shaped end 17, Which, as the lever is raised or lowered, bears upon or releases the valve 18 in the valve-seat.

To the end ot' the lever is attached a small rod 19, which is connected at its other end to the center or the Float O, which may be of any Suitable construction. In the shank of the valve-seat is secured the induction-pipe l?, which is connected at its other end to the supply-source. (Not shown.)

The operation of the valve mechanism is as follows: As the Water enters the valve-chamber ot' the trough, the oat is raised, Which lifts the handle of the lever gradually as the supply increases, closing the valve and stopping theflow. The Water has during this 0p eration entered the drinking-compartment of the trough, where, if by use it is depleted in volume, the iioat is lowered and the valve affected and opened just to the extent of depletion, and thus the supply is kept at about the same level all the time.

l. In a pig-trough, the combination of the base-pieces L, extended beyondV the sides of z 5 the trough and provided with standards A and platforms K, the trough arranged between the standards and having communieating partitions, the cross-pieces B, secured across the top of the trough on the standards, the cross-piece C, the top rail D, arched out on its under side, the covers E E', and an inlet-pipe having a valve Within the covered part of the trough, all substantially as described. 35

2. The combination, with the pig-trough, of a valvemechanism, consisting of a valve-seat M, provided with a threaded shank and a valve, a leverpivotedin supports on the valveseat and formed with an eccentrically-shaped end to bear on the valve, a link fixed to the end of the lever, and a float attach-ed to the other end of the link, substantially as described.
